Apache configuration problem for several apps

Thanks for looking into it... not sure if you did anything specific but everything except Dropboxmanager started working again. 

I did get this error when trying to restart apache2:

service apache2 restart
[....] Restarting apache2 (via systemctl): apache2.serviceError: No space left on device
^[[AJob failed. See system journal and 'systemctl status' for details.
 failed!

So I did a quick google search and added "fs.inotify.max_user_watches = 262144" to sysctl.conf

nano /etc/sysctl.conf

then ran 

sysctl -p

and restarted apache2 after which everything ran again

service apache2 start
[ ok ] Starting apache2 (via systemctl): apache2.service.
